New description: [New technical field] The new type relates to a condenser microphone. More specifically, a condenser microphone with a shockproof and moisture-proof unit is provided on the sound hole. % [Prior Art] Generally, a condenser microphone widely used in a mobile communication terminal or an audio system is constituted by a biasing element, a pair of diaphragms/back plates for forming a capacitor that changes in accordance with sound pressure (c) And a junction field effect transistor (JFET) that is used to buffer the output signal. This typical mode of condenser microphone is manufactured by integrally assembling a vibrating plate, a spacer ring, an insulating ring, a back plate, a conductive ring, a printed circuit board (PCB) in a housing, and then crimping the end of the housing ( Curling). Further, as shown in the first drawings (a) and (b), a plurality of sound holes 20a are generally formed in the casing 20 of the condenser microphone, and the external sound is prevented from flowing into the inside of the microphone through the sound hole 20a. The sound quality of the microphone is lowered. As shown in the second and third figures, the nonwoven fabric 10 is adhered to the outside of the microphone housing 20, or the metal sheet 10' which acts with the nonwoven fabric is adhered to the inside of the microphone. However, when the nonwoven fabric 10 is adhered to the outside of the microphone casing 20, it is necessary to add not only the manufacturing procedure for adhering the nonwoven fabric 10 but also the inconvenience caused by the exposure of the nonwoven fabric. In order to solve such a problem, in the case where the metal piece 10' which acts on the inside of the microphone case 20 is added to the inside of the microphone case 20, there is a problem that the thickness of the condenser microphone is increased correspondingly and the smoothness is lowered. M331726 In particular, as shown in the third figure, when the metal piece is mounted to the microphone, the pole is attached. When assembled, the pole of the vibrating plate is moved to the metal piece, so that the central part of the metal is vibrated. The (membrane) side is deposited, and the smoothness of the metal piece is broken, and the metal piece is brought into contact with the vibrating film to cause a defect in the vibrating film. That is, the metal piece is in contact with the vibrating film, and a flaw is generated on the vibrating film, which is a cause of poor reflow of the smd. Further, as shown in the third figure, the structure in which the metal piece (10) is transferred to the inside of the ear has the following problem: when the constant temperature/humidity test is performed, moisture remains on the metal piece to cause a defect. [New content] In order to solve the above problems, the purpose of the present invention is to form a condenser microphone with a shockproof and moisture proof single body in the sound hole towel body of the body. The purpose of the dry brush circuit is that the condenser microphone of the present invention comprises: a pair of pure vibration and a back plate shape, and a side surface and a side wall of the ramie suction body are formed by the bottom surface and the side wall. The dust and the thirsty ur are formed into sound holes, and the anti-vibration and moisture-proof unit of the sound hole for preventing the outer material 2 is formed into a body. The micro-hole or port element is formed in the sound hole of the housing, and the defensive and moisture-proof unit is reinforced by the bracket. The shock and moisture-proof sheets are formed on the surface of the towel at one or at least two. 70, or the shock-proof and moisture-proof unit is formed on the entire bottom shoulder M331726. According to the present invention, in the condenser microphone, a shock-proof and moisture-proof unit for preventing external dust or moisture from flowing into the inside of the microphone through the sound hole (none The woven fabric, the metal sheet, and the like are formed integrally with the sound hole of the casing, and the problem that occurs when the nonwoven fabric is exposed to the outside of the casing or inserted into the inner space of the casing is solved. That is, the present invention can solve the problem caused by the exposure of the nonwoven fabric and the corresponding increase in the thickness of the condenser microphone when the metal sheet acting on the inside of the microphone housing is added to the inside of the microphone housing, and can also be solved to be mounted inside the casing. Caused by the smoothness of the metal sheet

The internal structure of such a condenser microphone is just an example, and the present invention can be applied to microphones of various structures. As described above, according to the present invention, when a screen that performs the same function as the conventional nonwoven fabric is directly provided on the sound hole of the casing, it is not necessary to adhere the nonwoven fabric to the outside of the casing as in the prior art. Since the metal piece is attached to the casing, there is an advantage that the microphone assembly process can be shortened and the thickness of the microphone can be reduced. In particular, when a metal piece is added to the inside of the body, the addition of the metal piece causes a decrease in smoothness, and the % causes various defects. However, the assembly of the condenser microphone of the present invention does not require a metal piece, and therefore has a good smoothness. .

Referring to the seventh drawing, in the process of manufacturing the casing 302 by the micromachining technique, fine holes or screens 304 are formed in the sound holes 302a to prevent external dust or moisture or the like from flowing into the inside of the microphone through the sound holes 302a. In the case of the seventh figure, the number of the sound holes is the same as that of the previous embodiment, and therefore detailed description thereof will be omitted. • * · . * In the above embodiment, a cylindrical microphone has been described as an example. However, this is merely an embodiment. The present invention can be directly applied to microphones of other shapes such as a microphone having a polygonal shape.
